T o @ZZ 'whom t may concer/11,.'

Be it known that I,JOHN ANDERSON, a citizen of the United States of America,and a resident of the city of St. Louis and State of Missouri, have invented certain newand useful Improvements in Attaching Devices for Shoe-Heels, of which the following isa full, clear, and exact description, reference being had0 to the accompanying drawings, forming a part of this specification.

This inventionrelates to improvements in attaching devices for shoe heels, and more particularly to an attaching deviceadapted for use with resilient heels made of rubber, or the like. A

Prior to this invention, rubber heels have been secured to shoes through the medium of nails which are driven into the soles of the shoes. According to the usual practice, cach nail is provided with a head which lies in anopen pocket at the bottom of the heel, and l have found that small rocks, gravel, or the like, are sometimes forced into the open pocket where they bear against the nail head, with the result ofgradually foreing the sharp upper end of the nail through the insole of the shoe. This is especially true of rubber heels which yield, or weark away, inresponse to upward thrusts on the nail heads, so as to permit vertical displacemont of the nails.

The object of my invention is to prevent vertical displacement of the heel-attaching device. Briefly -stated the device I have shown to illustrate the preferred,l form of the invention includes a nail having a head which engages a lower abutment in the shoe heel, and this nail is also provided with a shoulder engaging a substantially non-yielding abutment at the upper portion of the heel to limit upward movement of theJ nail. Although upward displacement of the nail is prevented by the non-yielding abutment, the nails and abutments do not impair the resilient properties of the heel, the resilient material being free to yield between the upper and lower abutments. These abutments are preferably metal washers. An upper washer coperates with a shoulder onl the nail to prevent upward displacement of the nail, while a lower washer is yieldingly mounted between the nail head and the resilient heel-material.

ing device embodying the features of this Invention.

.Fig II is an enlarged fragmentary vertical section, illustrating portions of the heel and sole members, and showingone of the attaching devices as it appears when the heel is secured to the shoe. i

Fig. III is a plan View of a portionof the heel, showing the upper washer at the top face of the heel. i

To illustrate the invention I have shown a shoe provided with an insole 1, an outsole 2 and a heel A preferably made of rubber or other resilient material. B designates nails driven through the outsole 2 toV secure the heel. v The heel is provided with vertical nailreceiving openings each of which is en# Vlarged at its lower end to forma pocket 3 for a nail head 4. A lower abutment 5, preferably in the form of a metal washer, is located at the top ofthe pocket 3, and an upper abutment washer 5 Vis located at the top of the resilient heel. The nail Bis provided with a shoulder 6 engaging the metal washer 5 and a reduced extension 7 passing through the washer 5 and outsole 2, the sharp upper end of saidreduced extension being clenched onto the top face of the outsole 2. The upper washer ,is provided with a relatively small nail-receiving open-` ing through which the reduced extension 7 passes, while the lower washer 5 is provided with a larger iopening adapted to receive the body of the nail. The top faceof the heel A is `provided with pockets adapted to reoeive the upper washers 5', 4and the top faces of these washers are preferably flush with the top face of the resilient heel, The outer margin of each lower washer 5 is preferably embedded in the resilient heel, but the central portion of this lower washer is exposed at the top of the pocket 3 to receive thenail head 4.

After the heel has been secured to the shoe, each upper washer 5 engages the bottom face of the outsole 2, which is usually made of leather and the shoulder 6 on the nail engages the bottom of this washer 5 so as to prevent upward displacement of the nail. The upper washer may be considered as a non-yielding abutment, for its top face engagesa relatively firm portion of the shoe, and as a consequence the nail will not be displaced upwardly in response to upward thrusts on the nail head. However, theV Vwasher v does not impair the resilient properties of the heel.

VIt will thus be VVunderstood that the at# tachingrdeviee herein shown positively prevents upwardV displacement of theV nails,

thereby limiting/the motion-of thenails in such agmanner that the nail points cannot be projectedinto the heel of the wearer of Athe shoe,pandthis is accomplished without materially impairing the resilience. of vthe heel.. A Y 4 I claim:
